Power Step
« on: July 01, 2022, 02:25:54 pm »
we bought a 2013 3100 PC, it had 2 prior owner's that didn't believe in maintance, sooo, i'm fixing a FEW things, most of the front end steering parts, 6 tires, 4 shocks, at 39,000 it needed all of it, realign front end.  now getting down to less to do, batteries had no water so after water and a good charge they seemed ok, 3 days of not plugged in and new story, batteries are bad, replaced them but now the step hasn't worked since they went dead, don't see a reset, can't find a bad fuse, any idea's?

Jim, although I've had one issue with my power step, it wasn't power related so I've never had occasion to trace the power feeds myself.
However, based on information previously posted in the forum, there are two Phoenix-installed fuses in the driver-side under-dash/foot-well/kick-panel area.  There is a 5-amp fuse that feeds the door switch, and a 25-amp fuse that feeds the step motor.  That's probably the place to start. 

If you haven't already used the forum search function, you should get familiar with it.  There is many years worth of trouble-shooting and repair information on here and the search works pretty well if you will put in a specific term or a phrase in "quote marks".  You can usually pull up something that helps.

That little push button switch in the door controls the steps when the door is opened.   They are notorious for causing problems and easy to test.  Just take it out of the door frame and make sure the wires are not corroded and you can use a meter to see if the switch functions.  Or, you can simply short it out across the two connections and see if the steps operate.   

I have fixed mine a couple of times without even removing it by just giving the button a few circular twists which seems to remove some corrosion inside the switch itself.

Hi, I actually had issues with my button last week on a trip.  Kept going in/out on its own.  I tested the push button and all was good.  So I lengthened the bolt in the door that depresses the button a few turns and presto.  Fixed.

If the steps don't move at all no matter what, this is not your answer. There is a switch inside the house door that locks out the steps. If the switch is on, the steps don't move until you turn on the ignition then they pull in. Our steps were doing the in and out thing while driving so we keep that switch on so they stay locked out all the time. We think they did it while stored and it drained out truck battery.

Here are the trouble shooting steps.
Troubleshooting and Test Procedures
The Step Test Procedures are provided to troubleshoot and test all Kwikee® Electric Step functions. The
procedures are designed to initially check the basic functions of the step separately from the RV wiring to
determine whether or not the step is malfunctioning. The procedures test various components of the step
until the source of the malfunction is located. Using the procedures will shorten and reduce the time spent
troubleshooting.
Read the entire procedure prior to testing.
Some portions of the test procedures require additional equipment. This equipment includes:
• Voltmeter
• Well-Charged 12V DC Automotive Battery
• 4-Way Connector/Pigtail Part Number 369243.
Testing The Step Assembly
1. Inspect the step for visible damage that might restrict step operation.
2. Obtain a 4-way pigtail connector Part Number 369243.
3. Disconnect 4-way connector on underside of step and connect the step-half of the connector to the
4-way connector pigtail (Fig. 3, Fig. 4 and Fig. 5).
4. Set a fully charged 12 volts DC automotive battery beside the step.
Note: Do not allow the battery terminals to come in contact with the step. Complete a ground for the step
tests by connecting a 10 AWG wire from the negative battery terminal to the green ground wire of
the control unit.
5. To supply power, attach the red wire from the pigtail to the positive battery terminal. The step will
extend.
6. With the power and ground connections complete, all functions of the control unit can be checked
at the four wires of the pigtail. The brown wire is the door switch, the white wire is the step lockout
switch, and the yellow wire is the ignition override.
7. To retract the step, touch the brown wire to the negative battery terminal.
8. To extend the step, remove the brown wire from the negative battery terminal.
9. To test the ignition override feature, extend the step. With the step extended, connect the white wire
to the positive battery terminal and attach the brown wire to the negative battery terminal. Next,
touch the yellow wire to the positive battery terminal. The step should retract. Remove the brown wire
and the step should extend.
10. If any of the step functions do not work, the source of the malfunction is either in the control unit and/
or the motor. Proceed to the “Testing the Motor” section.
If all of the step functions do work, the malfunction is either in the door switch, step lockout switch, or the
vehicle wiring. Proceed to “Testing the 4-way Connector” section.
To test the “Auto Extend” feature:
1. Touch the brown wire to the negative battery terminal to retract the step.
2. While holding the brown wire to the negative battery terminal, remove the yellow wire from the
positive battery terminal.
3. Touch the white wire to the positive battery terminal. The step will stay retracted.
4. Now, remove the brown wire and the step should extend.
5. Next touch the brown wire to the negative battery terminal. The step should stay extended.

Here is the link to the manual it has a good wiring diagram that will help you troubleshoot your steps https://lci-support-doc.s3.amazonaws.com/manuals/steps/ccd-0002616.pdf

Also just an FYI, be very careful of the step and your fingers.  The step has a lot of torque and will remove a digit very quickly. I was amazed at how much torque that motor assembly actually can achieve.
Very Respectfully

Also, as you are troubleshooting, DO NOT get directly under the step!! If it starts working you do not want to get in its way with your body.
The pdf referenced above helped me fix my step problems.
BTW I did not get the pigtail. I just measured the voltages at the connector, but my steps had power.
For such a simple circuit it can be really confusing.

My step was working backward and it turned out to have the wrong switch ( N/O instead of N/C) and the motor power leads reversed.
Good luck.
